Editing Absolute space and time (section)

==Special relativity==
The concepts of space and time were separate in physical theory prior to the advent of [[special relativity]] theory, which connected the two and showed both to be dependent upon the reference frame's motion. In Einstein's theories, the ideas of absolute time and space were superseded by the notion of [[spacetime]] in [[special relativity]], and curved spacetime in [[general relativity]].

{{anchor|Absolute simultaneity}}'''Absolute simultaneity''' refers to the concurrence of events in time at different locations in space in a manner agreed upon in all [[frames of reference]]. The theory of relativity does not have a concept of absolute time because there is a [[relativity of simultaneity]]. An event that is simultaneous with another event in one frame of reference may be in the past or future of that event in a different frame of reference,<ref name="Ferraro" />{{Rp|59}} which negates absolute simultaneity.
